Crop Damage

Freezing temperatures in Florida pose a threat to crop health. Susceptibility to cold damage varies depending on the plant species and cultivar. Not sure if your crop is at risk? Refer to the Florida Automated Weather Network (FAWN) guide to determine the critical freezing temperature for your crop. You may also find this Review of Critical Temperatures for Key Central Florida Crops by Gary England, Multi-county Extension Agent, to be a useful guide. The only good news about the freeze is that you may see fewer insect problems. After you have protected your crops from freezing temperatures, scout your crops for pest activity prior to applying pesticides. Consult with your local cooperative extension office or crop-specific pest management information for additional details.


The table below links to extension documents that provide more information on how to protect your crops from damage during this period of cold weather.
